Can You Leave Eggs Out Overnight?

Have you ever left eggs out on the counter overnight and wondered if they’re still safe to eat? It’s a common question that many people have, and it’s important to know the answer to ensure you and your family stay healthy. In this article, we’ll explore how long eggs can be left out, what happens when they’re left out, how to tell if they’re still safe to eat, and tips for preventing contamination. We’ll also cover what to do with leftover eggs and why it’s crucial to follow food safety guidelines.

How Long Can Eggs Be Left Out?

Eggs are perishable items that require proper storage to maintain their freshness and safety. According to the United States Department of Agriculture (USDA), eggs should be stored in the refrigerator at a temperature of 40°F (4°C) or below. However, there are times when eggs can be left out at room temperature, such as during meal preparation or when transporting them from the grocery store to your home.

So how long can eggs be left out before they become unsafe to eat? The answer depends on a few factors, including the temperature and humidity of the room, the age of the eggs, and whether they have been washed or not.

Generally, it’s recommended that eggs not be left out for more than two hours at room temperature. If the temperature is above 90°F (32°C), eggs should not be left out for more than one hour. This is because bacteria can grow rapidly in warm and humid environments, which can lead to contamination and illness.

Factors That Can Affect Egg Safety

As mentioned, there are several factors that can affect the safety of eggs that are left out. One of the most significant factors is age. Fresh eggs have a thicker, more protective shell that helps keep out bacteria and other contaminants. However, as eggs age, their shells become thinner, making them more susceptible to bacterial infiltration.

Another factor is whether the eggs have been washed or not. When eggs are washed, the protective coating on the shell is removed, which can increase the risk of bacterial contamination. For this reason, it’s recommended that you don’t wash eggs unless they have visible dirt or debris on them.

What Happens When Eggs Are Left Out?

When eggs are left out, they can undergo several changes that can affect their safety and quality. These changes can include:

Changes in Appearance and Texture

When eggs are left out, their yolks and whites can start to separate, and the texture can become runny. The yolks can also develop a flat and watery appearance, while the whites can become cloudy and gelatinous. These changes can make the eggs less desirable to eat, but they don’t necessarily mean they’re unsafe.

Risk of Bacterial Contamination

Leaving eggs out at room temperature can increase the risk of bacterial contamination, particularly if the eggs are older or have been washed. The most common bacteria that can affect eggs are Salmonella and Campylobacter, both of which can cause food poisoning if ingested.

Health Risks Associated with Consuming Contaminated Eggs

Consuming contaminated eggs can cause a range of health problems, including diarrhea, nausea, vomiting, fever, and abdominal cramps. In severe cases, it can even lead to hospitalization and death. Certain populations are at higher risk of complications from food poisoning, such as young children, pregnant women, and people with weakened immune systems. Therefore, it’s crucial to take precautions to prevent contamination and ensure the safety of the eggs you consume.

How to Tell If an Egg is Still Safe to Eat

Visual Inspection

One way to determine if an egg is still fresh is to look at its appearance. Fresh eggs should have a clear, smooth, and uncracked shell. If the shell is discolored, cracked, or has visible signs of dirt or debris, the egg may not be safe to eat.

The Float Test

The float test is a quick and easy way to check if an egg is still fresh. To perform the test, fill a bowl with cold water and gently place the egg in it. If the egg sinks to the bottom and lays flat on its side, it’s fresh. If it stands upright on the bottom or floats to the top, it’s no longer fresh and should be discarded.

Odor Test

If you’re still unsure whether an egg is safe to eat, you can also perform an odor test. Fresh eggs should have a neutral odor, while spoiled eggs will have a foul or sulfurous odor.

Cracking Test

If you’ve determined that an egg is safe to eat, you can also perform a cracking test to check its freshness. Fresh eggs should have a firm white and a rounded, centered yolk. As eggs age, the whites become thinner and spread out, while the yolks become flatter and less defined.

Preventing Egg Contamination

Preventing Egg Contamination

The best way to prevent egg contamination is to take proper precautions when storing, handling, and preparing eggs. Some tips to follow include:

Proper Storage Methods

As mentioned earlier, eggs should be stored in the refrigerator at a temperature of 40°F (4°C) or below. Keep eggs in their original carton, as it can help protect them from temperature fluctuations and prevent contamination from other foods.

Handling Eggs Safely

When handling eggs, it’s essential to wash your hands thoroughly before and after touching them. Avoid cracking eggs on the edge of bowls or countertops, as this can increase the risk of shell fragments getting into the egg. Instead, use a flat surface or the back of a spoon to crack the egg. Additionally, avoid using eggs that are past their expiration date.

Cleaning and Sanitizing Surfaces and Utensils

To prevent cross-contamination, it’s crucial to clean and sanitize surfaces and utensils that come into contact with eggs. Use hot, soapy water to clean cutting boards, countertops, and utensils, and rinse them thoroughly. You can also use a solution of one tablespoon of bleach to one gallon of water to sanitize surfaces.

What to Do with Leftover Eggs

If you have leftover eggs that you’re unsure what to do with, there are several options for using them up. These include:

Hard-Boiled Eggs

Hard-boiled eggs are a versatile and easy-to-make snack or addition to meals. To make hard-boiled eggs, place them in a pot of cold water and bring to a boil. Once the water boils, reduce the heat and let the eggs simmer for 10-12 minutes. After that, remove the eggs from the pot and place them in a bowl of cold water to cool. Hard-boiled eggs can be eaten on their own, sliced on salads, or mashed into egg salad.

Omelets or Frittatas

Omelets and frittatas are a great way to use up leftover eggs and vegetables. To make an omelet, beat the eggs with a fork and pour them into a hot, greased pan. Add your desired fillings, such as cheese, vegetables, or meat, and fold the omelet over. To make a frittata, sauté vegetables in a pan and pour the beaten eggs over them. Let the frittata cook for a few minutes on the stovetop, then transfer it to the oven to finish cooking.

Baked Goods

Eggs are a common ingredient in baked goods, such as cakes, cookies, and bread. If you have leftover eggs, consider baking a batch of your favorite treats. Some recipes may call for only egg whites or yolks, which can be useful if you have an uneven number of leftover eggs.


In conclusion, it’s not safe to leave eggs out overnight or for extended periods at room temperature. Bacteria can grow on the eggs, which can lead to food poisoning and other health complications. To ensure the safety of the eggs you consume, store them properly in the refrigerator, handle them safely, and check their freshness before consuming them. If you have leftover eggs, there are many ways to use them up, such as making hard-boiled eggs, omelets or frittatas, or baked goods. By following these tips, you can enjoy the many benefits of eggs without putting your health at risk.
